I have a problem since today if I want to accelerate further in the fourth gear. It occurred, several times, when I got up on the highway and wanted to accelerate quite normally. The engine turns in the fourth gear at approx. 2500 rpm. further up, but there is no real drive. first I thought that it might be smooth and therefore the wheels would spin. But that’s not so, the DSTC does not start either. Does anyone have an idea what that could be. Tomorrow I will be on After all, the moose was there for customer service only last week.
